1. Heat oven to 350 F and prepare an 8x8 inch baking dish by covering with cooking spray and lining with parchment paper. Set aside.

2. In a large mixing bowl, combine oats, protein powder, cinnamon, salt. Stir. To the same mixing bowl, add peanut butter, honey, almond milk and vanilla. Mix until fully incorporated. Fold dark chocolate chunks into the batter. 

3. Pour mixture into the prepared baking dish and use slightly damp hands to press firmly agains the edges. Pay particular attention to the corners. After pressing the bars into place, I like to use a damp rubber spatula to ensure a smooth top layer and smooth edges.

4.  Bake for 19-21 minutes, until edges begin to crisp. Remove from oven and cool completely before removing from the pan. Use a sharp knife to cut into individual bars. Serve immediately OR .. wrap individually in parchment paper and store in an air tight container that has been placed in the refrigerator or freezer.
